Following the references in the manual I end up at: • _Integers and comma-separated integers_. Both patterns denote generation numbers. For instance, ‘--list-generations=1’ returns the first one. And ‘--list-generations=1,8,2’ outputs three generations in the specified order. Neither spaces nor trailing commas are allowed. Have you tried 'sudo guix system delete-generations N'? It seemed to work for me. Kind regards, T G-R Sent on the go. Excuse or enjoy my brevity.
